Code P1223 MINI Description

The P1223 MINI trouble code indicates that there is a high input signal detected from pedal position sensor 2 in the vehicle's electronic control module (ECM) or engine control module (ECM). The pedal position sensor is a crucial component that measures the position of the accelerator pedal and sends this information to the ECM to adjust fuel delivery and engine performance accordingly. When the ECM receives a high input signal from the sensor, it means that the sensor is reporting a higher pedal position than what is actually being input by the driver. This can lead to incorrect fuel delivery, ignition timing, and overall engine performance.
